In this video: A box of Grape-Nuts actually contains “whole grain wheat flour, malted barley flour, isolated soy protein, salt, whole grain barley flour, malt extract, and dried yeast.” It also boasts a number of essential vitamins and minerals. From what I could find, the recipe has remained largely unchanged since its introduction over 100 years ago, save for making the switch to whole grains. So just how did Grape-Nuts get their misleading name?
